Celtic boss Brendan Rodgers has told Premier League clubs to get serous about Moussa Dembele.
Crystal Palace and Brighton are eyeing the Frenchman this month.
"Moussa has never once asked to leave Celtic," Rodgers said. "We brought him here as a talented young player at 19 and he has shown that talent.
"We have had one official bid for him that is nowhere near the value of what the value of Moussa is.
"But equal to that we have no interest in selling him."
